This is some insulation/padding left over from putting flooring down at home. It went between a hard wood sub floor and a top floor of engineered wood. It all went over water underfloor heating system (attached to a heat pump). It's silver on one side to let the heat through. To be honest, I didnt think I should have any insulation, but everyone I spoke to said I needed it. This is the one to use with under floor heating. It's 1m by just over 2m. It's 2mm thick. It's not much but I didn't want to throw it away. £1.16 is the cheapest I'm allowed to put it on ebay for, but you can have it for free. Collection is from near Epsom station. Thanks.
